doors, vacuum pumps, max bar

3 questions i hope some of you on the list can help me with:
1. i recently received a dent in my 5000cstq passenger rear door.
what years rear doors are the same style? i plan to repaint a used
one for now.
2. Where is the vaccuum pump for a 84 quantum gl located? i can't find
it anywhere and don't have a manual? (it's not under the back seat,
it's a wagen)
3. On the computer of my 5000 cstq, the max BAR i can get it to read
is about (1.2). Is this normal or should it be higher (i think)???
TIA,
